Description Boris Mironov 2010-04-08 01:28:55 UTC
Summary:

SELinux is preventing /usr/bin/qemu-kvm "read write" access on 001.

Detailed Description:

SELinux denied access requested by qemu-kvm. It is not expected that this access
is required by qemu-kvm and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.
